Animal 6

Question 1

____ allow their internal condition to change in repsonse to external changes

Answer 1

conformers

Question 2

why are conformers able to conform (2 reasons)

Answer 2

• may have tolerance for greater range of physiological parameters
• in very stable environment

Question 3

parameters some animals regulate

Answer 3

thermoregulation (temp)

osmoreuglation (body water, salinity concentration)

Question 4

_____ rely on metabolism as their major heat source

Answer 4

endotherms`thermoregulator

Question 5

_____ body temp depends on external environment

Answer 5

ectotherms; thermoconformers

- don`t spend energy on maintaining high metabolism

Question 6

true or false: evaporation is a source of heat loss. Why

Answer 6

yes, water carries heat away as it evaporates from body`s surface

Question 7

both ecto and endotherms have behavioural responses for heat gain and lost. intense examples:

Answer 7

migration, hibernation

Question 8

what happens during hibernation

Answer 8

reduced set point of body temp, takes lots less energy

Question 9

: relaxes allow diameter to increase, allowing more blood flow, look flushes, allows heat from blood to be transported away from body for cooling

Answer 9

vasodilation

Question 10

reduces diameter of vessels, happens when trying to conserve heat as it keeps heat away from surface of body where it could be lost

Answer 10

vasoconstriction

Question 11

how do ducks feet stay warm without insulation

Answer 11

“counter current” means opposing flows, currents going in different directions
veins and arteries are located right next to each other in this case. This allows heat from arteriel blood to move into vein blood. The artial blood losses heat to venus blood
– blood in core of body

Question 12

is the total concentration of all of those solutes

Answer 12

isomolarity

Question 13

a solution with higher solute concentration is a ____osmotic solution

Answer 13

hyperosmotic

Question 14

SOLUTION WITH LOWER SOLUTE CONCENTRATION IS A ____OSMOTIIC SOLUTION

Answer 14

HYPOOSMOTIC

Question 15

hyper and hypo osmotic refers to the fluid outside of inside cell

Answer 15

outside cell relative to inside cell

Question 16

can osoconformers (salinity conformers) live in all types of water

Answer 16

no, not fresh water, too low salinity

Question 17

to increase salt concentration inside their bodies, what do fresh water fish do

Answer 17

adds sodium to the chlorine that is actively transported into their cells

Question 18

explain salt glands

Answer 18

glands with counter fluid exchange to get most salt out of blood
as blood moves salt ions are transferred to low solute concentrate filtrate (high to low concentration)
